1. Please Observe the Following (continued) Never turn the unit on without the lamp connected to the power supply. The energy emitted from the end of the light guide can heat any surface that it is directed at. Care must be taken to determine the proper offset distance and exposure time. Turning the lamp on and off frequently will cause the UV output of the lamp to decline at a faster rate. It is recommended that the unit be left on during breaks and short down times. Avoid making sharp bends in the light guide, as this will cause a loss of UV energy or possibly cause permanent damage. To prevent permanent damage, the minimum bend radii are 2.4 inches for a single light guide and 1.6 inches for a dual light guide. The unit may be repaired only by a Loctite authorized service technician. 1.4 Field of Application, (Intended Usage) This Loctite UV CL15 Wand System is designed for use with Loctite products that cure when exposed to ultraviolet light produced by the unit. The UV energy is directed towards the product through a liquid filled light guide that is ordered separately. Several configurations of light guides are available from Loctite, including single and dual ended types. The unit is also capable of interfacing with an external relay or PLC circuit. 2. Description 2.1 Theory of Operation When the unit is switched on, electrical power is immediately supplied to the lamp and ignition should occur within several seconds. As soon as the lamp has completed the warm up cycle, an internal relay will change state, making a closure across pins 3 and 4 of the footswitch connector, (located on the rear panel of the unit). The front panel display will indicate the progress at the warm-up period. Curing takes place when the shutter is opened, allowing UV light to be directed from the end of the liquid filled light guide to the adhesive. The curing parameters, (UV irradiance and exposure time) must be determined before use. The UV irradiance, (the strength of the UV light), at the adhesive surface can be varied by adjusting the distance of the light guide from the bond. If the light guide is moved to within ½ inch of the adhesive surface, vapors from the curing process may build up on the end of the light guide, reducing the UV intensity over time. The UV exposure time required to complete the curing process depends primarily on the UV irradiance and the properties of the adhesive product.

2. Description, (continued) UV lamps undergo a gradual reduction in UV output over time and it is recommended that the lamp output be monitored on a regular basis. Frequently turning the main power on and off will increase the rate that the lamp degrades, therefore, it is recommended that the unit be left on during short work breaks such as lunch and other idle periods. The digital display is the user interface to the system. It is used to set and view the shutter ON/OFF time, number of cycles, lamp hours, and system hours. During a cure cycle the time and duration will be shown counting down for user viewing. The timed exposure cycle starts by momentarily engaging the footswitch or when an externally operated device such as a PLC makes a relay closure across pins 1 and 9 of the nine pin foot switch connection, XS-1, on the rear panel. In the manual operating mode, the shutter remains open for as long as the footswitch or alternate external device maintains contact between pins 1 and 9. Notice: The hour meter should only be reset when a new lamp is installed. 2.2 Operating Elements and Connections The front panel is a membrane control pad with an LCD display. The keypad controls all the major operating features.

4. Installation 4.1 Space Requirements A space of 12" wide x 16" deep x 9" height is required. It is important to have at least 8 inches of space behind the unit to insure proper airflow. Curing Wand System only needs to be connected to a 120V/60Hz outlet to operate. Do not block the intake and exhaust fans located on the back of the housing. The unit should always be operated with the rubber support feet resting on a flat surface. Do not operate with the unit resting on its side or at an angle greater than 15 degrees, front to back. 4.2 Connections WARNING! Make sure the power switch is OFF and the unit is unplugged before proceeding. - Plug the footswitch into the nine pin D-sub connector located on the rear panel. If the unit is being operated from an external processor, a closure across pins one and nine is required to actuate the shutter. An internal relay closure connected to pins three and four of the footswitch connector provides conformation that the curing lamp is on. When the lamp is not on, an open circuit exists across pins three and four. - Plug the power cord into the power module located at the bottom left of the rear panel. - Plug the cord into the electrical utility outlet. - Insert the light guide into the receptacle located on the left side of the front panel until it is fully engaged. 5. Operating the Unit Turn on the power switch located on the rear panel, above the power cord receptacle; the system takes just over a minute to warm up. If for some reason the bulb does not ignite, turn the power off, wait ten seconds, and turn on again to start the lamp. An internal relay will close across pins 3 and 4 of the rear panel D-sub connector, SX-1 once the lamp has warmed up. During the warm-up time, the LCD display will show a numerical percentage with an associated progress bar, to indicate the progression of the warm up sequence. During this time the shutter is disabled. Once the system has completed the warm up cycle the text message SYSTEM READY will be displayed on the screen.

5. Operating the Unit, (continued) At this time the operating parameters can be changed, or the existing parameters can be utilized. The footswitch can now be pressed or PLC output operated to initiate the operation of the curing unit. Using Foot Switch / Remote Device The shutter can be actuated using a foot switch or by other external devices such as a PLC. The foot switch connection is made up of a 9 pin D connector. In timed mode, making a momentary dry-contact relay closure across pins 1 and 9 will initiate cycling of the shutter. In manual mode, the shutter will remain open for as long as the pins 1 and 9 are connected. Front Panel Controls The system hours and lamp hours can be viewed by pressing the ENTER button. The system hours are a non-reset able timer that tracks the age of the unit. The lamp hour indicator is a reset able timer to aid in tracking the life of the bulb.

If a user selects a time below the minimum range the unit goes to MANUAL mode. In MANUAL mode the shutter is directly operated by the footswitch. If the footswitch is pressed the shutter will open, closing as soon as it is no longer pressed. Once this parameter is set press ENTER to continue. Shutter OFF Time Setting The next parameter that can be changed is the amount of time that the shutter is closed during a cycle. The time can be increased or decreased using the (+) or (-) buttons. The shutter close time can be set with the following limits: Time Base Min Time Max Time 0.1 sec.1 sec 24.9 sec 1.0 sec 25 sec 250 sec The time base automatically changes at 25 seconds. ENTER to continue. Once this parameter is set press Cycle Count The next parameter that can be changed is the number of cycles that will run during a single iteration. The number of cycles can be increased or decreased using the (+) or (-) buttons. The maximum number of cycles that can be run during a single iteration is 255. Once this parameter is set press ENTER to continue.

5. Operating the Unit, (continued) Lamp Hour Reset The lamp hour meter is used to keep track of the time that the given bulb has been in service. Once the bulb has been changed the lamp hour meter should be reset to accurately track the service of the new bulb. Determine if you would like to reset your lamp hour meter and make your selection using the (+) or (-) button. Once this parameter is set press ENTER to continue. NO is set as the default in case the user is cycling through the functions quickly. Save Parameter Changes At this point all the parameters have been changed to the user s preferences. These changes have not been saved to memory, and if they are not, all parameters will revert back to the previous values. At this point the user is prompted to save the changes. Determine if you would like to save the changes to memory and make your selection using the (+) or (-) button. Once the selection has been made, press ENTER to continue. Notice: At any time, while making changes to the parameters, if the user pauses for longer than 7 seconds, the display will return to the System Ready screen and no changes will be saved. 6. Inserting and Removing the Light Guides Be sure to remove the plastic end caps before attempting to use the light guide. If the free end of the light guide is secured at a fixed location, sharp bends should be avoided since this causes a decrease in UV power. Never pull on the jacketing portion of the light guide. During installation or removal, grasp the light guide on the strain relief nearest the input end of the light guide. 6.1 Installing single light guide Insert the large end of single light guide into the light guide receptacle located on the left side of the front panel. Push light guide firmly until it is fully engaged. Installing dual light guide Insert the dual wand light guide into the light receptacle and rotate. See section 6.2 Adjusting Wand for Maximum Output. Notice: It is important that the rotational position of a dual light guide be set to maximize the UV output for each wand. This setting is specific to each curing unit and light guide (See section 6.2- Adjusting Multi-Pole Light Guides).

Notice: Avoid shutting the main power off for brief periods of time. Frequent start-ups will cause the lamp to decay at an accelerated rate. If the system is shut down, wait a minimum of ten minutes before restarting. Once the lamp is ignited, allow it to operate for a minimum of fifteen minutes before turning it off. 6.2 Balancing Output When Using Multi-Pole Light Guides Required - Loctite 7020 UV Spot Radiometer P/N: 1406024 1. Insert the light guide into the light guide receptacle pushing it as far forward as it will go. 2. Tighten the set screw on to the light guide, (do not over tighten). 3. Set shutter timer to between 2 and 5 seconds. 4. Insert the one of the pole ends of the light guide into a Loctite 7020 UV Spot Radiometer, P/N 1406024. 5. Press the radiometer start switch and actuate foot switch to open shutter. 6. Release the radiometer start switch while the shutter is still opened. 7. Record the radiometer reading. 8. Position the second light guide pole in the radiometer and repeat steps 6 though 9.. 9. Compare the two radiometer readings. 10. If the lower reading is equal to or greater than 90% of the higher reading, the dual wand is balanced. 11. If the lower reading is less than 90% of the higher reading, loosen the set screw and rotate the light guide several degrees in the light guide receptacle. Use the set screw to re-secure the collar in that position. 12. Take and compare another set of radiometer readings. 13. Continue until the lowest reading pole is equal to or greater than 90% of the high reading pole. 14. Re-tighten set screw to lock the dual wand in position. Notice: If a radiometer is not available, it is recommended that Loctite Service be contacted at 1-800-LOCTITE (1-800-562-8483) to insure optimum performance when installing a new multi-pole light guide.

7. Care and Maintenance Notice: It is recommended that the UV output from the lamp be monitored regularly using a Loctite 7020 UV Spot Radiometer P/N: 1406024. If a radiometer is not used to monitor the lamp, it is recommended that the lamp be replaced when the LCD display indicates 1,000 hours of operating time has elapsed. It is normal for the lamp output to slowly decline over operating time, however, the effective life of the lamp will decrease significantly faster if it is turned on and off frequently. It is recommended that the end of the light guide be positioned no closer than ½ inch from the Loctite product being cured. The heat transmitted by the lamp can adversely affect the properties of the cured product or possibly cause damaged to the part surface. Notice: Vapors from some products may gradually accumulate on the end of the light guide, reducing the UV output. It should be inspected regularly and cleaned as necessary using isopropyl alcohol and a soft, clean cloth. Avoid placing sharp bends in the light guide. This reduces the UV output and may permanently damage the light guide. If the light guide is mounted on a fixture, secure it by the metal exit fitting and not the flexible plastic section. Be sure to remove the plastic end caps before attempting to use the light guide. Notice: The intake and exhaust fan filter elements should be replaced as needed to insure proper cooling of the power supply and UV lamp assembly. They should be inspected routinely. 7.1 Replacing the Lamp Do not touch the inside surface of the lamp reflector or the bulb. Contaminants from hands will create hot spots and cause the module to fail prematurely. If either one is accidentally touched, carefully wipe clean using soft cloth and isopropyl alcohol. 1. Switch the power off and unplug the unit. 2. Allow several minutes for the installed lamp to cool. 3. Using a 3/32 Allen wrench, loosen the four button head screws that are on the sides of the top cover. 4. Lift the cover straight up off of the chassis. This will allow access to the bulb reflector assembly. 5. Unplug the lamp from the power supply (see photo #1)
